Black powder was the first explosive ever invented, and was the primary propellant used firearms around the world for many centuries. However, in modern times, smokeless powder has largely replaced black powder as the most common firearm propellant.

A cartridge, [1] [2] also known as a round, is a type of pre-assembled firearm ammunition packaging a projectile (bullet, shot, or slug), a propellant substance (smokeless powder, black powder substitute, or black powder) and an ignition device within a metallic, paper, or plastic case that is precisely made to fit within the barrel chamber of ...
The combustion products of smokeless powder are mainly gaseous, compared to around 55% solid products (mostly potassium carbonate, potassium sulfate, and potassium sulfide) for black powder. [1] In addition, smokeless powder does not leave the thick, heavy fouling of hygroscopic material associated with black powder that causes rusting of the ...
[3] [4] Higher velocities may be obtained using special cartridges drilled out to accept shotgun primers, which provide higher velocities, and some fast draw competitions allow the use of a small amount of black powder or black powder substitute to provide higher velocities for certain events. Commercially produced wax bullets are also ...
Cordite is a family of smokeless propellants developed and produced in Britain since 1889 to replace black powder as a military firearm propellant. Like modern gunpowder, cordite is classified as a low explosive because of its slow burning rates and consequently low brisance [not verified in body].
